Sports news from Los Angeles and beyond

Manny Pacquiao's promoter Bob Arum said Wednesday that rival promoter Golden Boy Promotions in Los Angeles has until 5 p.m. Monday to match Arum's offer to Juan Manuel Marquez for a November bout against Pacquiao.

In a telephone conversation with The Times, Arum shed some new light on the offer he has presented to Marquez. The promoter said Marquez will receive a minimum $5 million for a Pacquiao fight, with more possible in pay-per-view money.

And if Marquez wins the welterweight bout at a catch weight of 144 pounds, Arum said, the world lightweight champion from Mexico would be guaranteed a $10-million pay day for a rematch.

That's where Golden Boy -- which promoted Marquez for most of the last decade -- might have a difficult time matching the finances.

Golden Boy Chief Executive Richard Schaefer said Tuesday he could possibly match Marquez against world welterweight champion Victor Ortiz later this year.

Schaefer said, "I have not received any communcation from Juan Manuel Marquez."

Also Wednesday, Arum said former world welterweight champion Antonio Margarito will now be examined next week in Los Angeles by a respected eye doctor who will assess if the detached retina Margarito suffered in his November 2010 loss to Pacquiao is career-ending.
